There is research in the psychiatric (and sociological) literature about anniversary/holiday reactions. This is not just about murder, but about how some people with psychiatric or psychological symptoms experience a worsening near certain holidays. Depression near the anniversary of a loved one's death. Depression at Christmas if no longer around family, etc. Anxiety near the anniversary of a bad event (even though no conscious thoughts about the event in some cases).
It's strange to think about women disappearing on Thanksgiving or Christmas or Mother's Day (the three most mom/family-oriented holidays). If this is a crime committed by a stranger or casual acquaintance of the Morphew's, one has to wonder why they were out and about seeking opportunistic victims (or revenge) on or about Mother's Day.
If it's someone more closely associated or inside the family, then it's a vicious attack both on a mother and on her children, ruining forever this holiday. On Mother's Day, I often post pictures of my late mother on FB, my daughters post about their grandmother, most of my friends do the same. One friend does not do this, posts beautiful pictures of her flower garden - and I know why she doesn't post pictures of her mom and I know how terribly sad she still is about her mother's passing (of old age), while she was far far away.
So. Regardless of how this happened, my heart goes out to those two happy, adorable young women who forever have to live with awful memories of Mother's Day, may feel cynical and jaded, may forever have relationship issues because of this. I hope they get all the support and help that they need, but as far as we know, their father is living apart from them in a friend's house and, last we heard in MSM, was inviting contact only via a friend's phone. Hopefully that has changed.
One other strange thing: LE has apparently told the family not to make public statements (see the CrimeOnline articles) although one unnamed relative still made a few helpful but vague comments. Presumably, the daughters have also been told not to speak to media? Because if my mom were missing and I did not suspect my dad one little bit, I would be out in public saying exactly that. I also would do this regardless of what LE told me to do, but that's just my personality. Also, I'm not 20 or 17. At 20, I would have been at my dad's side in the event of anything happening to my mom. I would have spoken to media if she was missing. I realize everyone is different, but those of us following since Day 1 are still perplexed by the total radio silence in this case.
Also, can anyone find Suzanne's name in NAMUS? I thought Colorado Missing Person's procedures call for local LE to make that entry into NAMUS. Maybe I'm just not finding it - so if anyone with more experience or an account at NAMUS can check, please post. I don't think she's there. This is, IMO, a criminal investigation and not a missing person's case.
